For many, a restful night’s sleep feels elusive. While countless remedies are touted, from warm milk to meditation, a growing body of research suggests a surprisingly effective solution may lie in regular physical activity. Specifically, a recent meta-analysis indicates that high-intensity yoga is more strongly associated with improved sleep than walking, resistance training, or other forms of exercise. This finding offers a promising, non-pharmaceutical approach for the millions struggling with sleep disturbances.
The comprehensive study, published in 2025 in Sleep and Biological Rhythms, analyzed data from 30 randomized controlled trials encompassing over 2,500 participants across more than a dozen countries. Researchers at Harbin Sport University in China found that engaging in high-intensity yoga for less than 30 minutes, twice a week, yielded the most significant improvements in sleep quality. The benefits were observed within as little as eight to ten weeks, suggesting a relatively quick path to better rest.
Yoga’s Edge: How It May Promote Sleep
While exercise in general is known to benefit sleep, this research highlights yoga’s unique advantages. The study doesn’t definitively explain *why* yoga appears particularly effective, but several physiological mechanisms are likely at play. Yoga isn’t simply about physical exertion; it integrates physical postures with focused breathing techniques. Research indicates that controlled breathing activates the parasympathetic nervous system – often referred to as the “rest and digest” system – which counteracts the body’s stress response and prepares it for sleep.
some studies suggest yoga can influence brainwave activity, potentially promoting deeper, more restorative sleep. The practice may also help regulate cortisol levels, a hormone associated with stress, which can interfere with sleep when elevated.
Comparing Exercise Types and Past Research
While yoga emerged as the most effective exercise in this meta-analysis, walking and resistance training also demonstrated positive effects on sleep. Walking ranked as the next best option, followed by strength-based exercises. This reinforces the broader understanding that regular physical activity, in any form, can contribute to improved sleep.
However, the findings aren’t entirely consistent with previous research. A 2023 meta-analysis suggested that aerobic exercise or moderate-intensity exercise three times a week was most effective for individuals with sleep disturbances. Interestingly, that earlier study also noted that yoga showed more significant sleep benefits than other exercise types, hinting at a consistent, though perhaps underappreciated, effect. The differing results may stem from variations in study design, participant characteristics, and the specific types of yoga and aerobic exercises examined.
It’s also important to note that categorizing yoga as strictly aerobic or anaerobic can be challenging, as its intensity can vary significantly depending on the style and practice. The New York Times explored this nuance in 2017, highlighting the complexities of classifying yoga within traditional exercise categories.
The Importance of Individualized Approaches
The researchers at Harbin Sport University caution against overgeneralization, emphasizing that “caution should be exercised when interpreting findings from studies on sleep disturbances, given the limited number of studies included and the unique characteristics of the sleep disturbances population.” They also stress the need for further, high-quality research to confirm these findings.
the best exercise for sleep is the one an individual will consistently practice. “Our bodies and brains are all different,” and there’s no single solution for insomnia or other sleep problems. The study’s findings suggest that incorporating high-intensity yoga into a routine – even just twice a week for under 30 minutes – can be a valuable tool for improving sleep quality. However, it’s crucial to listen to your body and consult with a healthcare professional before starting any new exercise program, especially if you have underlying health conditions.
Another recent study published in 2025 found that tai chi was effective for improving sleep, comparable with cognitive behavioral therapy for insomnia (CBT-I). While CBT-I initially showed greater improvements, the benefits of tai chi caught up after 15 months, suggesting its long-term accessibility and integration into daily life contribute to sustained sleep improvements.
The researchers concluded that “a yoga exercise prescription, conducted twice weekly for 8–10 weeks, lasting ≤ 30 min per session, and of high intensity, is the most effective approach for improving the sleep quality of individuals with sleep disturbances.”

As research continues to unravel the complex relationship between exercise and sleep, one thing remains clear: prioritizing physical activity is a powerful step towards better health and a more restful night. Future studies will likely focus on refining exercise prescriptions for specific sleep disorders and identifying the optimal intensity and duration for maximizing benefits. The researchers plan to continue monitoring long-term outcomes and exploring the underlying mechanisms driving these positive effects.
